The USDA NDL has removed the USDA Database for the Added Sugars Content of Selected Foods from the NDL website. This is due to constant changes in formulations for commercial, multi-ingredient foods, the primary contributor of added sugars to the diet. NDL is not recalculating added and intrinsic sugars at this time, in part, because brand name market shares and ingredients are changed so rapidly that these estimates are more a temporary cross-section in time than fixed values. No method can analyze for added sugars so their amounts must be extrapolated or supplied by food companies, many of which are not willing to make public such proprietary information. The Agricultural Research Service (link is external) provides additional information about this decision.
